The imperative demand for a motor possessing the elements of
safety, economy, simplicity and durability, has called forth, dur-
ing the past century, the best efforts of the most eminent engi-
neers both of Europe and America, as evinced by the many
varieties of motors at present in existence, operated by gas,
atmospheric air, carbonic acid, ammonia, electricity, etc. ; but,
till very recently, steam has been pre-eminent in utility, notwith-
standing its danger, high rate of maintenance, and total unfitness
in the hands of inexperienced persons.
A careful examination of all the motors mentioned above,
shows that atmospheric air is the only agent at all likely to
successfully compete with steam, from its universal presence, its
low capacity lor heat, and its capability of producing great power
when properly applied ; and in this proper application consists
the superiority of the
RIDER COMPRESSION ENGINE.
Aa its name implies, the chief and distinguishing feature of
this Engine is, the nse of highly compressed cold air, the thorough
heating thereof , without change of volume, and its efficient
expansion to a point to or below the pressure of the atmosphere,
thereby completely utilizing all the force or mechanical effect
po8iible. k ,

All these changes are consecutively and rapidly effected in this
motor, without the use of valves, springs, levers, or, in fact, any
delicate parts whatever, the moving parts being reduced to the
lowest possible number, viz: the pistons, shaft, and connections.
ADVANTAGES POSSESSED BY THE
OVER ALL OTHER MOTORS.
1. — Its perfect safety under all circumstances and conditions.
Unlike a Steam Engine, no explosion is possible. Unlike a
Caloric Engine, it emits no heated air or sparks of carbonized
oil, as all the air is continuously retained within the Engine, and
cooled down below the temperature of the surrounding atmos-
phere, at each revolution, thus making the Engine even safer
THAN AN ORDINARY STOVE.
2. — Its Extreme Simplicity. It has not a Valve, Spring,
Cam, Eccentric, or any loose or delicate part about it to get
out of order.
3. — Its Great Economy. Twenty to thirty pounds of coal
being sufficient to run a one-horse power Engine ten hours.
4. — It is Perfectly Noibeless.
5. — Having no valves, there is no exhaust or escape of burned
oil, or any noxious odor.
6. — iTjtEQUiREs no Engineer, and little skill to operate it, as
it has no boiler and uses no steam, and only requires that the
tire be occasionally replenished and bearings oiled.
7. — It does not Increase Risk of Fire or Cost of Insurance.
8. — It requires less space and less fuel than any other motor
of equal power, %

For this purpose we can justly say they are the most perfect
engines ever constructed. Their marvelous simplicity, absolute
safety, great economy, and wonderful effectiveness rendering
them far superior to any other Pumping Engine in the market.
Each Pumping Engine is furnished with the Rider Patent Rol-
ling-Valve Pump — double acting — which works at any speed
without the slightest shock or noise. The PumpTs placed on
the side of the cooler, and works directly from the compression
piston (as may be seen by reference to the cut), thus insuring
perfect rectilinear motion; and all the water is passed directly
from the pump through the cooler on its way to the tank or out-
let, making the most complete arrangement possible.
b THE BIDEK COMPRESSION ENGINE.
The Six-inch, or Household size, will very easily deliver nine
hundred gallons of water per hour, at an elevation of sixty or
seventy feet from the surface of phe well or cistern; or a pro-
portionate quantity at a greater elevation; and will use, when
running ten consecutive hours, from twenty to thirty pounds of
coal only, requiring scarcely anymore attention than an ordinary
stove. This size is particularly adapted for supplying city and
suburban residences, stores, tenement houses, hotels, boarding
houses, &c, with water, as the expense of furnishing an abun-
dant supply is thus reduced to an unprecedentedly low figure,
being really only from one to two cents for a thousand gallons.
These Engines are also well adapted for nurseries, breweries,
tanneries, supplying fountains, irrigating lands, pamping water
for cattle, furnishing water for hydraulic elevators, &c.
The next larger size, viz , the ten-inch Engine, we can confi-
dently recommend as
The Great Railroad Pumping Engine of the Age.
For this purpose, i. e., supplying railroad water-stations, and
other places where considerable water is required, it stands alone, '
UNRIVALED AND PRE-EMINENT.
DESCRIPTION AND OPERATION
RIDER COMPRESSION ENGINE
As may be seen by the sectional cut on the seventh page, the
Eider Compression Engine consists essentially of a compression
cylinder A, and a power cylinder B, with their respective pistons
C D, and connections, and a regenerator S.
The lower portion of the compression cylinder A is kept cold
by a current of water which circulates through the cooler E,
which surrounds the lower portion of the cylinder, while the
lower portion of the power cylinder is kept hot by the action of
the fire below the heater F.
The heating, and also the cooling of the air, is instantaneoiisly
effected by its alternate presentation to the surfaces of the heater
and cooler, in a thin annular sheet, such being found by exper-
ience to be the only correct method of rapidly and thoroughly
effecting changes of temperature in air.
This is accomplished as follows : —
The compression piston G extends downwards to the base of
the Engine, and is a trifle smaller than the interior of the cooler
F, thus leaving a thin space on all sides for the air to pass down-
ward and become thoroughly cooled on its way to the bottom,
and through which space it flows on its way back to the heater.
The power piston D likewise extends downwards into the heater
F, which in shape resembles the bottom of a champagne bottle,
that is, rising in the center, and presenting to the action of the
fire, a narrow annulus all around the bottom. "Within this heater
is the telescope G t which is a thin iron cylinder, about one-fourth
TBS BIPCB COMTRESSION BNOIXX. 9
of an inch leas in diameter than the interior of the heater. It
ia fitted to the interior of the power cylinder B, and extends '
nearly to the bottom of the heater. Its office is to cause the
air which flows from the .-omprtssion cylinder to be presented
in a thin sheet all around the interior surface of the heater, and
particularly li the lower and hotter portion. By this means
the air is thoroughly and rapidly heated.
The same air is used continuously, as there is neither influx
nor escape, the air being merely shifted from one cylinder to the
Between the compression and power cylinders is situated the
regenerator //, the economical value of which cannot be over-
rated. This regenerator is composed of a number of thin plates
slightly thickened at their edges, which, while affording a free
passage to the air, subdivides it into thin sheets. It is so placed
between the cylinders as to be traversed by the air in its passage
each way between the hot and cold cylinders. Thus the heat
is alternately abstracted from and returned to the air in its pas-
sage backwards and forwards through these plates, imparting
great economy and steadiness of power to the engine.
The other portions of the engine are readily understood on
inspection of the cut. The two pistons are attached directly to
to the crank J /, (which stand at an angle of about 95 degrees
from each other, the crank of the power piston being in
advance, ) by simple connecting rods J J ; and all the movements
of the various parts are uniform, being solely derived from reg-
ular, circular and rectilinear motion ; and as there are no com-
plicated parts, and none of the irregular intermittent impulses
which characterize Caloric Engines, a high rate of speed and
smooth action may be safely and easily obtained.
K K are the packings which are in duplicate for each cylinder.
The lower one has its lap downwards to resist the escape of air
below the piston, while the upper one has its lap upwards to
prevent the lubricating material from entering too freely into
Between them is the Belief King, which is so constructed as
to almost entirely relieve the friction of the packings.
10 THE EIDER COMPBESSION ENGINE.
Z is a simple check valve which supplies any slight leakage of
air which may occur. It is generally placed at the back of the
engine, at the lower part of the compression cylinder, but is nec-
essarily shown in the sectional cut on the side.
The operation of the engine is "briefly as follows : —
The compression piston C first compresses the cold air in the
lower part of the compression cylinder A into about one-third
its normal volume, when, by the advancing, or upward motion
of the power piston D, and the completion of the down-stroke
of the compression piston C, the air is transferred, from the
compression cylinder A, through the regenerator H, and into the
heater F, without appreciable change of volume. The result is
a great increase of pressure, corresponding to the increase of
temperature, and this impels the power piston up to the end of
its stroke. The pressure still remaining in the power cylinder
and re-acting on the compression piston C, forces the latter
upward till it reaches nearly to the top of itB stroke, when, by
the cooling of the charge of air, the pressure falls to its mini-
mum, the power piston descends, and the compression again
begins. In the meantime the heated air, in passing through the
regenerator has left the greater portion of its heat in the regen-
erator plates, to be picked up and utilized on the return of the
. air towards the heater.
Heatek. The heater is made by a peculiar process of our own,
whereby the metal is rendered very dense, and refractory to the
action of heat, thus greatly increasing its durability.
Packings. The packings are simple discs of leather, and will
last a very long time without renewal : those on the hot cylin-
der are kept cool by a small stream of water, which circulates
round the upper portion of the cylinder, so that there \i no dan-
ger of o v ©rheating them.
Connecting bodb. The Connecting rods are of the best known

construction. Their ends are made of gun metal, connected to-
gether by a tube, in which is fitted a rod, extending from the up-
per to the lower brass, and so arranged that one key, capable of
nice adjustment by nuts, at once takes up the lost motion on
both upper and lower brasses. This tube also permits the oil
to flow down to the lower brass, and thus Wi etuis are lubricated
from the oil cup at the same time. It will be seen that this
construction is at once efficient and durable ; no loose straps,
gibs or other pieces are used, and there is no chance of consequent
Watbb. As before stated, in the Pumping Engines the whole
of the water pumped is passed directly from the pump through
the cooler, thus effectually and instantaneously cooling the heat-
ed air, which passes down the interior of the cooler on its way
to the b'lttom. Avery small pump is also furnished with the
Power Engines, which is attached like the large pump of the
Pumping Engine, to the side of the cooler, and a small stream of
water is injected with each stroke of the piston. This may be
returned, if desired, to the barrel or reservoir from whence it ia
taken, until the water becomes in time too warm for effective use;
or, it may be allowed to run to waste, which is preferable where
water is not too scarce, as the cooler the compression cylinder is
kept, the better. Where a pressure of water can be obtained,
the small pump may be disconnected if desirable, and a very
small stream allowed to flow into the cooler, and pass out at the
No pains are spared to make these Engines perfect in every
respect. The materials and workmanship are of the best qual-
ity, and we are confident that the public will find them unequaled
for compactness, design, efficiency, and general usefulness.

HtTNTINOTON, HOPKINS & Co.,
The Rider Compression Engine which you
furnished me has now been in operation nearly two months, and
is working well. It runs one Taylor Cylinder and four Gordon
Presses easily, with power yet to spare.
For purposes requiring from one to three-horse power, I
believe the Rider Compression Engine is without an equal,
M it is simple in construction and does not require the services
of an engineer ; no extra rate of insurance is exacted; and it
requires but little more fuel to generate the necessary power
than I use in my stove during the winter season. For my pur-
poses, it cannot be equaled by anything within my knowledge.

The Rider Pumper (Household size) you set up in my apart-
ment bouses, "The Lexington," on 49th street, last year, has
proved itself in all respects better than you claimed. You guar-
anteed it to me to pump 800 gallons water an hour, but on a test
it pumped 1260 gallons. It has never had one cent for repairs
put on it, and is in as good order as when new. To pump for
the five houses it has to work a half hour morning and night.
For pumping I think it has no superior, and shall probably put
one in my houses in 50th street.

Enclosed please find cheek in payment for the Household
Pumping Engine purchased of you some two months since. I
am perfectly satisfied with it in every respect, and can pump from
the cellar of my French flat houses to the roof (five floors),
eight hundred gallons of water per hour, at a merely nominal
cost of running. The Engine can be seen any day in my
houses, corner of 91st street and 3d Avenue.

New Yobk, Dec. 15th, 1875.)
The six-inch Compression Pumping Engine which you sent
me for my house in Orange, N. J., is all that you represented it
to be. The cost of running it is comparatively nothing — about
two quarts of coal (nut size) will fill my tank, which holds about
one thousand gallons, drawing the water from either well or cis-
tern, and elevating it to the tank, 30 feet. The steam engine
which I first had for the same purpose cost so much for fuel and
to keep in order, that I could not afford to run it. It was a con-
stant source of fear that it might blow up ; consequently I did
not dare to leave it while steam was at a pressure in the boiler.
Your engine pumps the tank full while I am eating my supper,
and requires no more attention after it is properly oiled and
started than the kitchen fire.
My servant (cook), makes the fire in the engine before I return
home from business, so that all I have to do is to oil and start it.
She can run it as well as I can, but I generally do it for my own
amusement. My architect, Mr. J. Frank Lyman, of Orange,
N. J., says you may refer to him..

The Household Kider Engine I bought of you several months
since, has proved itself fully as good as you guaranteed it, as
regards economy, simplicity and power. It runs two barrels of
gum and alcohol, and one small mill for grinding gum. It does
this with perfect ease, thUB doing away with the expense and
annoyance of having boys to do the work now done by the
engine, requiring little or no attention, only enough to keep up
a small fire ; for parties desiring small power, I should recom-
mend the Household Engine as being the best small motor I ever
saw, and as being the extreme of simplicity.
